Alternative to NTG (Nuclear Test Gage) Assays of Reactor Solutions.

摘要

This report proposes a replacement analysis system for liquid samples now submitted for measurement on the 321-M Nuclear Test Gage (NTG). Systems have been evaluated explicitly for rework Process Water (D20), Emergency Cooling System solution (ECS, Polybor) and Supplementary Safety System solution (SSS, Gadolinium Ink) from the reactor areas, but could be extended to other types of solutions as well. The proposed replacement analysis system could be located in the Laboratories Department or in one or more reactor areas. The new system would eliminate contamination and radiation exposure to 300-Area personnel from this source. Assays would be available on a more timely basis because assay times are shorter than for the NTG and it would be unnecessary to wait for a convenient time to reconfigure the NTG for this special function.
